Saguaro cactus adaptations

Answer 1

The adaptations of the cactus includes small and spiky leaves that reduce evaporation of water. It also prevents loss of water. The cactus has also a thick and juicy stem that stores water. It carries out photosynthesis like any other normal green plant.

Waxy leaves, long roots, have needles

Cactuses have many adaptions to survive in dry, hot regions. Such as:

- Being greyish/silver in color: To reflect heat of the sun and reduce water loss

- A swollen stem: To store water

- Rolled up leaves (only in certain cacti) to reduce surface area that is exposed to the sun, therefore preventing water loss

- Covered in thorns: Helps protect the plant from animals trying to eat it

Answer 2

· The Saguaro Cactus only lives in the Sonoran desert of South East California, South of Arizona, and the North West of Mexico. · This cactus can grow as tall as fifty feet, weigh up to several tons, and live for two hundred years · It has a smooth waxy skin and is covered with two-inch needles. The saguaro's sharp spines protect it from harm · In desert there is very little water, therefore the cactus has a storage place named the 'ribs' where the water is stored when it rains. · The Accordion-like pleats in its skin expand in the rain, storing extra water for the long dry times. · It also has an amazing root system which is very shallow for such a big and heavy plant. It has a large net of roots that extend far away from its trunk, collecting more water when it rains. · The Saguaros grows arms to increase it reproductive capacity.

Answer 3

1. Its expanding trunk allows it to take in and store a great deal of water when water is available. 2. It does not need a lot of water to survive. 3. The flower opens on cooler nights and is closed during the heat of midday.

Answer 4

Two major adaptions of the Saguaro cactus are the spines and the folds along the stem. The spines grow 2 inches long and form in bundles of about 20 along the stems of the cactus to act as a defense. These spines also point downward to channel rain into the accordion like folds of the cactus. These fold will also swell during a rainfall in order to absorb more water and store it for the dry periods.
